ACS Hydrobar® Woodbead is a single-pack, waterborne impregnating water repellent for exterior timber. Once completely cured, the product has high water-shedding properties and a long-lasting, pronounced beading effect. Suitable for application to bare softwoods and hardwoods.
Laboratory testing has shown marked reduced levels of water uptake, even after 4000hrs QUV (approximately 10+ years). Noticeable beading on field trial product, even after 17 years exposure in an Alpine environment.
Note: Surfaces treated with ACS Hydrobar® Woodbead will not accept waterborne or solvent-based paints until several months of weathering has taken place.
ACS Hydrobar® Woodbead is a single-pack, ready-to-use aqueous solution, of functional silicone resin. Milky white colour on application that dries clear.
ACS Hydrobar® Woodbead imparts water and dirt resistance to exterior timber joinery, including cladding, sheds, fences, noise barriers, decking and seats.
ACS Hydrobar® Woodbead protects timber from moisture but allows the joinery to age naturally.
ACS Hydrobar® Woodbead contains no fungicides or UV controlling pigments but will inhibit organic growth through its water repellent properties.
ACS Hydrobar® Woodbead improves the life expectancy of timber species vulnerable todecay, such as pine and lower grade softwoods.
ACS Hydrobar® Woodbead can be used with the ACS Lignotec Wood Treatment if control of sapstain and wood decay fungi is required. Apply the ACS Lignotec Wood Treatment one to two days prior to application of the ACS Hydrobar® Woodbead to allow time for it to be adsorbed by the timber and begin its work.
After application, ACS Hydrobar® Woodbead leaves little or no visible signs of application, except areas treated with ACS Hydrobar® Woodbead will not darken when wet.
Take the usual labour hygiene into account.
PPE should be worn during application. See our Safety & PPE Products.
Consult label and material safety data sheet for more information.
Ensure all surfaces are clean, dry and free of oil, grease and loose or flaking material such as bark.
ACS Hydrobar® Woodbead is suitable for application to bare timber. Any paints, stains or varnish must be completely removed prior to application.
Remove all organic growth such as mosses, lichens, moulds and fungi with Green Gone Path & Patio Cleaner. The glossy surface of prepared timber (PAR) should be lightly abraded with wire wool or medium grade Aluminium Oxide paper to reduce surface tension and increase porosity.
Old, ‘silvered’ timber should be rubbed-down to remove degraded material to expose new wood. Mask off any glazing and cover plants. If spraying, do not allow spray-drift to come into contact with sensitive surfaces, such as vehicles.
Product may settle during storage and transport, so shake the contents well before and periodically during use.
Apply by brush, deep, pile roller or conventional garden sprayer.
Apply an initial coat, starting from the top of the substrate to be treated, working down the surface and allowing excess liquid to run down.
Once the whole surface has been treated, but before the initial coat has dried, apply a second coat (so called wet-on-wet application).
Once completely dry, further applications may not be adsorbed.
Remove splashes from glass and plant life immediately or mask-off or cover prior to application.
Approximately 4-8m² per Litre depending on the porosity of the timber.
Do not apply if there is a likelihood or rain, fog or frost before the coating has completely dried, if the surface is wet or if within 3°C of the dewpoint.
